Electronic Blood Pressure Monitor
As a medical diagnostic device, the airtightness performance of an electronic blood pressure monitor directly affects measurement accuracy and reliability. Poor airtightness can lead to:
| Issue | Consequence |
|---|---|
|
|
Leakage causes pressure drop, resulting in lower blood pressure readings |
|
|
Continuous air leakage forces the air pump to operate under excessive load |
|
|
Severe leakage may cause abnormal inflation of the air bladder |
|
|
Failure to meet medical device certifications such as YY 0670 and ISO 81060 |
By implementing a comprehensive airtightness testing system, we ensure that every blood pressure monitor leaving the factory meets medical measurement accuracy requirements. For specific testing solutions tailored to your product, our medical device testing experts are available for professional consultation.
Detailed Professional Testing Solutions:
| Direct Pressure Decay Method | Detection sensitivity: ±1mmHg | Test pressure range: 0-300mmHg (expandable to 500mmHg) | Applicable parts: Whole air circuit system testing |
| Differential Pressure Method | Detection sensitivity: ±0.5mmHg | Especially suitable for micro-leak detection | Applicable parts: Critical sealing components (e.g., valves, connections) |
| Flow Detection Method | Quantifiable leakage rate | Applicable parts: Air pump output performance testing |
Typical Testing Process Demonstration
Taking an arm-type electronic blood pressure monitor as an example:
| Testing Phase | Specific Steps |
|---|---|
| Pre-Treatment Phase | Device self-check and zero calibration |
| Select corresponding test program (adult/child mode) | |
| Connection Phase | Quickly connect the monitor's air port to the fixture |
| System automatically identifies device type | |
| Testing Phase | Automatic inflation to set pressure (typically 200mmHg) |
| Begin testing after 10 seconds of pressure stabilization | |
| Monitor pressure decay value within 60 seconds | |
| Judgment Phase | System compares measured values with standards |
| Automatically generate test report | |
| Audible and visual indicators for test results |
